Breach (de_breach) is a community-made bomb defusal map added on the July 31, 2019 update. It has been added in competitive in Scrimmage mode. The map takes place in winter, since some snow is seen on the ground outdoors. It has been removed from the game on March 31, 2020, along with Studio.
This scenario pits the Professionals against the FBI as they attack Tangent corporate headquarters with the intent to destroy critical infrastructure: the server room or the executive building.
- There's a Half-Life lambda logo on a building out of bounds, just outside long A and above what seems to be a cafeteria.
- An easter egg is hidden on the map. Around the map, security cameras can be found mounted above doorways. Four of them will light up in red when a player character is standing near them. If all four light up, a security camera above a doorway located in Upstairs next to Terrorist's Spawn will light up. If a player then interacts with the door handles of the doorway, they will see a cutscene where they slide off the slide located in Terrorist's Spawn in first person.
- The player's first-person view is detached from the player character and put into the slide when interacting with the door handles. The player character will still be standing at their original location, unable to be controlled for the duration of the cutscene.
